vm crash with latest 64bit Pharo vm on mac

Andrei Chis-2
 
Hi,

With the latest 64bit Pharo vm running with Pharo64-60451.image on mac I sometimes get a vm crash during long computations that take more than 1gb of memory. I do not have a reproducible use case but it seems to happen more often if I increase the eden size. 

Not sure if it's related to the compactor bug but here is the report I get when the crash happens, in case it provides any hints.
